This invention relates to a road implement. It.

has for one object to provide a scraper-which may be detachably mounted upon an automobile I or an automobile truck or on a vehicle of desired sort. In'the f'ormhere shown it is mounted upon a motor truck. a I

Another object is to provide aroad implement adjustably' positioned upon a" vehicle. A further object is to provide a mounting for such an im-'.

l0 plement so arranged that theimplement itself may be positioned at different angles with respect to the direction of movement of the vehicle and so that it may be raised and lowered and retained parallel to the ground, irrespective of its position of, angular: adjustment.

Other objects will appear from time r ,the specification and claims. v a a r The invention is'illustrated more or less diagrammatically in the accompanying drawings,

f The details of the vehicle upon which the implement and itssupporting frame are mounted form no essentialpart of the present invention 49 and a vehicle and frame of any sort might be used; i a The frame, as illustrated diagrammatically herewith, comprises sidemembers A, A. A is an axle upon which the frame maybe mounted in 5 any desired manner. A are wheels. A bumper or other cross, member A is attached tothe front of the frame. i V a The implement assembly includes asub-frame whichis fixed uponthe vehicle frame. It may be :0 mounted thereon removably but in the operation of the device, it is not movable with respect to the frame and it furnishes, therefore, a relatively fixed base for the support and adjustment of the implement itself. Thesub-frame includes a pair of preferably parallel side members B, B which may be of any suitable section. The side frame member 3 may be made ,of a unit or may be built up, as shown particularly in Figure 4. At their rear ends the'sidemembers Bare attached to across member B by means of uprightmembers B and the'cross member B is supported members A by means of amember l? which fits over this flange and is fastened to the crossmember B by bolts 3*. Adjacent their forward ends the side frame members B are supported from the vehicle frame cross member A by bolts B which eng e a strap 13' which rests upon the upper surface'of thevehicle framecross member A. Fastened to the forward end of the subframe is a generally pointedmember B". As shown. it comprises a single unitary strapdike member. It might of course, be made in any other way. Adjacent its forward end is positioned a base plate B. Upon this base plate 1B is screwed, bolted, or otherwise fastened, the base 13' of an hydraulic or other pressure cylinder B Intermediate its ends the cylinder B" is in conpreferably upon the lower flange of the frame tact with an angle or plate 3" to which it is held by a U-bolt B" which is fastened to one flange of the plate or angle B". Extending downwardly and rearwardly' from the plate 3" is a pair of braces 13" which, at their upper ends, are attached to the plate or angle 3 and at their lower ends are attached to the member B". A tube or conduit B servesto supply fluid under pressure to the pressure cylinder 3 It may be "connected with any suitable source of pressure.

the .ends of the supporting frame member B 5 is a pair of stirrups B"; The stirrups are perforated adjacent their tops to receive latch pins B" which slide through the perforations in the member 18 and through corresponding perforations in the member B A bearing and guiding member 13 may be attached to =the'frame member 3 to provide a better bearing for the pin B A stop B extends through each. of the pins B" and a compression spring B" is positioned about each of the pins B" and forces each pin downward to the limit controlled by the stop pin B so that the latter is'normally in contact with the down in its lowermost position. A notch B in the side of the'stirrup B" receives the pin B" and holds the latch pinup out of engagement with the plate C.

or it may have plate members welded or otherwise fastened to it. In the form here shown two members C", C are fastened to the bottom of the plate C and furnish a support for short rods C, the plate C, the members C and the short rods C comprising a yoke structure mounted for pivotal movement about the axis of the pin C. These rodsare perforated as at C and the plate C is itself perforated above the rods so that the latch ins B" when free to do so, may extend through the perforation in the plate Cv andinto the perforation C as shown in detail in Figure 4. The plate itself is provided with other perforationsC. There maybe any suitable number ofperforations C, the arrangement being such that when the plate is rotated from the position shown in Figure 1 to the position shown .for exampleyin Figure 5, the latch pins will penetrate into the perforations C and hold the plate in that position. The number of such perforations dependsupon the various desired positions of adjustment and any suitable number and arrangement of perforations may be adopted. At their outer ends the rods C are preferably reduced in size and provided with ball members C". To support the blade or other implement or tool,;there is provided a pair of forwardly extending arms D, D. These maybe, as shown, of angular cross section, or of any other desired shape. Each is provided preferably adjacent its rear end with a socket D which engages one of the balls C' so that the armsD are supported through the rodsC and the balls C" in a ball and socket arrangement from the plate C and pivotal movement of the plate will move one arm backward and the other forward, as shown for example in Figure 5. Intermediate its ends and. opposite the pressure cylinder B 9, each of the arms D is provided with an upwardly extending perforatemember D to which is fastened one end of a chain D At its upper end each.

of the chains D is fastened to a plate member D which rests upon and is'preferably attached to the upperend of a piston D which is forced out of the pressure cylinder by the pressure within it. The plate D is preferably pivotally mounted for swinging movement upon a pin D.

. Thus it can swing and accommodate itself to the adjustment of the blade or other implement as shown in Figure. 5. A split ring or compression collar D" is. mounted about the piston and is provided with a locking screw D and a handle D' by means of which the collar may be locked about the piston to prevent its beinglowered below the desired height. The collar might be dispensed with but when it is used it makes it unnecessary to retain pressure in the cylinder.

Once the piston has been raised to the desired height, the collar being locked prevents lowering of the piston and so holds the parts at the desired position without the necessity of maintaining pressure within the cylinder. Intermediateits ends each of the arms D is provided with a stirrup D within which a" latch pin D is jour- Thus the plate. is supported benaled. The pin is arranged to protrude below the bottom of the arm D and may be additionally supported in a bearing member D fastened to the member D. A limit pin D limits the outward or downward movement of the latch pin and a compression spring D" forces the pin downward when it is free to do so. latchpin is raised the limit pin D may be engaged' in a notch}? in the stirrup D to hold it in raised position. At its forward end each of the arms D is provided witha generally upstanding bearing sleeve D for a pivot pin D 'D"', D are reinforcing webs attached to the sleeves D and to the arms D.

E is a blade or implement-carrying plate. As

shown it includes two generally rounded, rearwardly extending portions E E each of which is at or near the ends of "the horizontal frame member E An upper horizontal frame member E .joins the side members E Angular members E may be used to join, themember E with the. plate E. One or more bracing strap members E is provided to connect the plate E with the frame structure Just described. and particularly to connect it to the upper frame member E. E is the board portion of a scraper. As shown, it is provided with a rearwardly bent lower portion E which is in contact with the lower horizontal frame member E*. E is a road" contacting blade which is detachably mounted by a series of bolts E. It may be of any desired shape; and size and is preferably made detachable'so that it may be removed after wear. The bladeserv'es additionally to hold-the lower edge E of the plate E i'against the frame member E H I F is an upper section formed as shown in Figure 2 of a generally curved, sheet-like member. It may be rearwardlybent along its upper edge as at F At its lower edge itis fastened to an angular frame member Fl. ,Any desired form of upwardly extending end frame members F may be .usedrandthe section itself is removably faste'ned'to' the lower section by a series of bolts F; F preferably overlies the side member E, as shown in Figure 2.

It will be realized that whereas we have herewith shownand described a practical operative Whatever the vehicle, the main frame of the assembly is attached to the forward end of the vehicle and thereafter, during the time that it remains upon the vehicle, it is fixed and the frame thus becomes in effect an extension of the main frame of the vehicle itself and it provides a support for the movable parts of the tool assemhly. The height of the blade or other implevment itself above the road surface is determined by the position of the piston in the pressure cyl- When the aoaaoes inder. This pressure cylinder may be of any desired type and may beconnecte'd with suitable source or pressure fluid. Since it rests upon the fixed frame and since the chains which it carries are"attached to the lifting and swinging arms which themselves carry the blade, the

latter and the arms whichbarry it are raised 'and' lowered' by raising and lowering the piston.

As a matter of convenience the locking ring D is provided so that once thepiston has been moved to its de'siredrheight by pressure it may ;be locked in that position and the pressure may be relaxed. Of course, thelocking ring gmight be omitted and the pressure retained. Also, in-[ stead of apressure cylinder-the piston might be raised by any other desired means, such as a screw or lever mechanism, but whatever the details of this construction, 'meansare' provided, resting upon the fixed frame, ior raising and lowering the swinging arms. 1 r

-When the'swinging arms D, D, have been raised to the desired height so that the bladefor other -road'implement is properly a'dJusted withrespect tothe road, surface, the angle of the blade with respect to thewline of travelmay bee adjusted. The blade itself is carried movably upon the two pins D" which are-mounted one at the end of each of the armsD. When the parts are in the position shown in Figure 1, the blade is arranged at right angles to the line 'of travel of "the vehicle and ,the. latch pins B" are in position in the holes C of the rods C? so thatthe ends of the arms D are held'in position. The latchpins D are" also engaged in the central holes E of the plate sections E so that the parts are all rigidly held in the position shown in'Flgyurel. i

If nowit is desired to adjust the angular posi tion of the blade from that showntin Figured to thatshown in Figure 5, all of thelatch pins are withdrawn and the parts are then pushed or otherwise moved into the position shown in may be raised and lowered with respect to the roadsurface to almost any desiredp ositionand that its angular adjustment with respect tomthe line of travelmay be varied. Whatever the angular positionof adjustment of the bladathe pivot point of the blade carrying, armsD always remains at the balls C! and thus the length of the arms, D isconstant no 'matterwhat the position of angular adiust'mentrand; if the blade has been moved. for exampleato theqposition shown in Figure 5 and it is desired then to raise y it, a raising of the piston D will raise'the blade and since the lever arms D, which carry the blade, are of constant length, the blade will rise and will remainparallel to the road surface. Thus, by the constructionshown, adjustment with respect to the road surface and angular adjustment are possible and no matter what the angular adjustment, any adjustment with 're spect to the road surface always leaves the lower edge of the blade parallel to the road surface. This is a point of great importance because it permits accurate and uniform adjustment of the blade with respect to the road surface, no matter what the angular adjustments! 'the blade with respect to the line of travel. Y
